[Plugin] bim-tools 0.13.4(june 22, 2015)

Dan Rathbun

Does anyone have tips on how to best implement the (back)slashes in file-paths cross-platform?

somepath = %q[a/path\to/some\sub\directory] somepath = File.expand_path(somepath)

Sorry, I can't get this to work on Mac.... bummer.

I had to edit the objectlibrary.rb file to insert "/btobjects.rb" instead of "\btobjects.rb", and this allowed the plugin to load without an error. However, all I got was a dialogue that didn't seem to work. Did I miss anything? Check out the image below.

All paths in Ruby should use forward slashes - this to ensure cross platform functionality.

Too bad I can't test it myself, the dialog is a webdialog, only tested on internet explorer.
I can however download safari for PC to test the javascript/html, I'll look into that.

During the past months I have re-written my bim-tools plugin from scratch, I think the new concept is a very solid foundation for expanding it into a great BIM-modeller in the SketchUp way of modelling.(I also simplified the dialog, hope it works on mac out of the box...)

The latest code is on google-code: http://code.google.com/p/bim-tools/

I'm currently hunting for bugs, brave people can give it a try , preview added to the post.

At this moment there is a toolbar with 3 buttons:

The first opens the webdialog with options for BIM elements.
the second cobnverts selected faces into "BIM objects"
the third, switches the display between the original "source faces," and generated "BIM" geometry.
The contents of the webdialog adapts to the selected BIM elements(will go wrong once in a while). BIM elements will transform with the source faces...

It is still very easy to screw up the model, for example:

scaling faces
"Splitting" of faces
simultaneously change "name" or "description" for several elements at once.
each edge can only have two faces
also connecting faces on the same plane still give an error message.

The project is getting much fun!!!

Preview, not ready for real use!

I had a quick look at the code - see it uses .set_html - which is bugged under OSX after Safari 5.0.6 update.
Made inline-comment in the Google repository for file: bt_dialog.rb

also made a couple of other notes.

Too bad .set_html is bugged, I rather liked this method for updating my webdialog. Do you have any suggestions on how to replace it? The only thing I can think of is a whole lot of javascript...

Thanks for looking into it, unfortunately I can't seem to find your comments in the google-code project. I don't have any experience yet with the code review functionality. Can you point me in the right direction? Any comments are most welcome!

I got half of your script working with a little aditional ruby to write a temp file and then use .set_file on mac.
I just realised it was with the oldest version, so if I try again with the latest it may all work...
L'll let you know.

Ha! good idea! a bit of a dirty hack, but sounds like a great solution while waiting for the sketchup team to fix the direct set_html method!

Thanks! when it works I'll gladly use it!

Well, I wouldn't hold my breath for that, because it's not actually broken... It's a security feature of webkit.

The server [in our case SU] creates the WebDialog headless when you use set_html.

By default WebKit blocks local file access, if there is no record of the 'user' is making or agreeing to the request.

When you use set_file the source is coming from a 'user/local' so WebKit allows that domain access to it's own resources.

If it's only the button images then encoding base64 is dead easy on mac.

Just downloaded the latest and there are path issues... john

Here is my workaround for the .set_html issue:

OK,
on the assumption your interested,
I added $: << '/Library/Application Support/Google SketchUp 8/SketchUp/Plugins/bim-tools' for now, to make sure the basic path gets through. Then changed the backslashes in two require statements and
this is what SU produces from your .set_html.

if I run this outside of sketchup it works, so I'll try my 'trick'...

I'll look at the css...

the changed code so far is just this, from line 31 in bt_dialog.rb

		
		# PC Load paths will have a ';' after the drive letter.
		@is_mac = ($LOAD_PATH[0][1..1] != ";")
		`rm /tmp/btDialog.html`
		@tmpPath=('/tmp/btDialog.html')
		@tmpFile=(File.open(@tmpPath, 'w+'))
		@tmpFile.rewind
		@tmpFile.puts html
		@tmpFile.rewind	
		
		
		self.walls()
		self.project_data()
		self.export()
		
		
    if  @is_mac 
		@dialog.show_modal
		@dialog.set_file(@tmpPath)
	else 
		@dialog.set_html( html ) 
		@dialog.show
		
	end
	#@tmpFile.close
	#File.delete(@tmpPath)

brewsky

Thanks John! It's getting somewhere!

For the new version I simplified the layout(less css), so that might already improve the looks...
I'll try to implement your trick in the new version.
And if it's a security feature... would it not be best to use the same temp file on windows? It might be marginally slower but would be a more "universal" solution...

For everyone interested... I have put another small video on youtube showing the progress on the new 0.10 version. http://youtu.be/J59EgH7LICs

The video is bad quality without comments or audio and the plugin is still buggy, but as you can see in the video that it's quite easy to convert existing sketchup faces to "BIM" elements, and these already move and stretch with the source faces!

brewsky

For the temp file, would it be a good idea to only check the OS using something like:


if ENV["TEMP"] != nil
  tempdir = ENV["TEMP"] # PC
else
  tempdir = ENV["TMPDIR"] # MAC
end

Ah! I see your workaround uses something like that!

thomthom

This is what I use:

<span class="syntaxdefault">module&nbsp;TT</span><span class="syntaxkeyword">;;</span><span class="syntaxdefault">System<br />&nbsp;&nbsp;TEMP_PATH&nbsp;</span><span class="syntaxkeyword">=&nbsp;</span><span class="syntaxdefault">File</span><span class="syntaxkeyword">.</span><span class="syntaxdefault">expand_path</span><span class="syntaxkeyword">(&nbsp;</span><span class="syntaxdefault">ENV</span><span class="syntaxkeyword">[</span><span class="syntaxstring">'TMPDIR'</span><span class="syntaxkeyword">]&nbsp;||&nbsp;</span><span class="syntaxdefault">ENV</span><span class="syntaxkeyword">[</span><span class="syntaxstring">'TMP'</span><span class="syntaxkeyword">]&nbsp;||&nbsp;</span><span class="syntaxdefault">ENV</span><span class="syntaxkeyword">[</span><span class="syntaxstring">'TEMP'</span><span class="syntaxkeyword">]&nbsp;).</span><span class="syntaxdefault">freeze<br />end</span>

Note the pattern that you don't need if else structure to pick between a set of variables that might be nil.

path = ENV['TMPDIR'] || ENV['TMP'] || ENV['TEMP']

[/code]

I know a lot of PC coders think this is the best and easiest place to write temp file to, but it returns
/var/folders/lN/lNON23AjHxezeYON7yETPU+++TI/-Tmp-/ and is only cleared on a after a FULL shutdown and StartUp.
the other is "/tmp", which clears after a restart [i.e. all most mac users ever do, and with a lack of crashes...]

It's actually one of OSX's shortcut's to "./private/tmp" and you often see ENV["TMPDIR" || "/tmp"] used outside of SU.

Yeah I figured that out from your example webdialogpatch file! There still is a lot of smooth looking rubyishness to learn

brewsky

@driven said:

so would you suggest something like this? (don't know how to shorten this)


if ENV["TMPDIR"] != nil
  tempdir = "/tmp" # MAC
else
  tempdir = ENV["TEMP"] # PC
end

btw /tmp sounds very logical, I would use that on linux too...

brewsky

This is what I have now, seems to work OK on windows. Do you see any problems for mac?
